Engine Replacement Interchangeability FAQ Guide

Q1: What engines can I use for a direct swap/replacement?
A1:
Any FS 2.0L from a 2001-03 Protege or Protege5, manual or automatic does not matter, you're swapping the engine not the transmisson, the flywheel and clutch will bolt up to the crank of the donor engine, just keep all your manual parts and pieces to swap over
1993-1997 MX6/Probe and 2.0L FS engines are available but not recommended because the cranks are not forged, and you will have to take it apart to transfer parts over, and high mileage on these engines.
1993-2002 626 also have 2.0L FS engines but only the 2000-2002 blocks should be used, some 99s depending on the production date. The difference is the crank was reported to be forged in the later year modelsQ2: What you must buy new or transfer over on all FS engines?
A2:
Main cap support plate, specific to MSP it has the turbo oil drain machined into it and is right above the oil pan.
Rear oil cooler, lines, oil filter stud
Intake manifold, valve cover, thermostat cover, heater bypass pipes, the coolant junction block, and the bracket around the side of the head above the junction block
Rest of your current Protege accessories and manifolds
If you use a non Protege cylinder head you MUST transfer the Protege cams, cam gears, valve cover over, crank pulley, ignition. You MUST use a non-distributor cylinder head.
98-99 626 FS have smaller intake ports and have different cams.
2000-2002 626 uses the same cams as Protege
Any other brackets or parts that broke as a result of the engine failure
Maintenance related parts and hardware. ex. clutch, timing belt, spark plugs, hoses, seals, gaskets, pumps, etc.
Good time to do the rear engine mount if yours is torn
Your existing transmission and drivetrain parts.Q3: Can someone show me a how to guide through the entire swap process?
A3:
Stop, step away from the forum, hire a competent mechanic before you fuck shit up even more. (rlaugh) If you are seriously competent and mechanically inclined, the available manuals online should tell you everything you need to know to do it. There is a reason why there are paid professionals in the field. So if you can't RTFM and understand the process, this applies to you. This is not a beginner's task. If you want to learn go enroll at a technical school for automotive technology. BTW, shops usually do charge more to fix something a DIY'er fucked up. http://www.floptical.net/mazda/

Q4: Where can I find places that sell engines?
A4:
Salvage yards in your area, if you find one local you wont have to pay to ship a big heavy pallet.

Q5: What about building the engine?
A5:
Read the FS engine build FAQ page. (http://***********************/fsengineguide.htm)

[DubbyDoo]

the engine support plate is diffrent from the auto to manual by the way I found this out earlier from a engine I had laying around

[DubbyDoo]

the starter on the manual car is a 3 bolt flange design but the starter on a auto is a 2 bolt

[SeR_Cyclops]

Nice Write up!!!! GOD it seems like everyday people are asking about motor swaps.

[SCMP3]

the starter on the manual car is a 3 bolt flange design but the starter on a auto is a 2 bolt

we found this out this past weekend when helping swap my buddies pro5 motor. we just drilled a whole threw the plate for the bolt.

[jagass]

Nice write up man...

[SpeedAdiction20]

Nice job, I'll be getting someone to swap my old MSP's engine with my brothers new/blown block, perfect timing!

Edit: also quick question, the replacement that we are doing, the blown motor has custom built valve cover and adjustable pulleys, and forged cams, so I am assuming that when doing the swap we will need to buy a full set of replacement gaskets for the whole engine, or can we get away with just the valve cover gasket, then I guess there is the exhaust and intake mani gaskets too.. so full replacements i guess huh?

i would buy the whole gasket set. its real complete for the money and guarantees you won't be missing anything

[SpeedAdiction20]

thanks Ken, was checking those out after I realized I would need them, it's never as easy as just a replacing things, always something else needed lol, but it looked like a great set. thanks as always

[Captain KRM P5]

no problem. we carry pretty much anything needed to get a broken or swapped FS on the road again, so hit me or JDM Sam up if you need it.

[JDM Sam]

You always replace the timing belt, tensioner spring, water pump, front and rear main seals, cam seals, valve cover gasket, intake and exhaust gasket, any other gasket that you expose through removal and installation, spark plugs, oil, coolant before you swap another engine in. It is future insurance knowing the maintenance was done, especially if you do not know the maintenance condition of the engine. See ANSWER #2

[SpeedAdiction20]

ok thanks for the info/help

[i like speed]

Why couldn't you use a mx6 or probe engine? Is the crank not forged in those or is there another reason?

[SpeedAdiction20]

they said you could use them, but it wasn't recommended, but i dono why

[Captain KRM P5]

real old FS engines do not have cam sensors or cam gears with magnetic pickups, so the car's ecu would not run the engine without these.

[JDM Sam]

Why couldn't you use a mx6 or probe engine? Is the crank not forged in those or is there another reason?
You just answered the question.
What Ken said is true, but it can be made to work, see ANSWER #2.

[SpeedAdiction20]

just thought of another question, when replacing a used engine, there any type of "break in period" or just go right after the swap back to normal driving?

[JDM Sam]

just top off everything and go.

[SpeedAdiction20]

nice, thanks again

[kyle's protege5]

i just got a great deal on a 95 probe fsde with 64k on it. Plan on using my cam gears, my head and intake, my crank and valve cover.

my cams got some groves from i'm guessing the ass bags that built my motor not cleaning it out good enough. changed the oil every 500 and popped a rod out the block at idle after only 1200. .... hope the crank is good.....

the only difference i see with the cams is the gear on the exhaust that drives the distributor. any body know the specs on them? If the piston smacked my head and messed it up (god i hope not, just had it all polished, ported, 3 angle valve job, new seals) i will use the head off the probe motor, and get it all redone, and just machine a plug for the distributor hole.

any other differences i should look for?

[kyle's protege5]

ok...... just found out something i did not notice before. My 95 probe block does not have a spot for the knock sensor.

Shit.


There is an unused hex head plug about 2 inches to the right. Cant i use that? from what i can find, the knock sensor just has to be solidly bolted into the block.

[justanothermp5]

so let me understand this, if i went to pull a part today and pulled the engine out of a 93 mx6 then it would fit correct? i pulled the valve cover off and it would fit any FS except it doesnt have a hole for the cam sensor so thats pretty much junk
but for 100 bucks thats a great deal on an engine...

so replace valve cover, use crank from protege engine, use head from protege engine

thats it or did i miss something

[Sport23]

You would want to use the head w/ valve cover from the protege, also the crank (should be forged.) So you are looking at $100 for a block, rods, pistons and a fair amount of work. Also, some of the older blocks dont have the hole for the knock sensor IIRC.

[JDM Sam]

Yeah, but don't bother using the 93-99 FS engines. The FS block was revised in the later year models to be stronger and the oil galleries and coolant passages improved. Also, someone said the older FS blocks didn't have a knock sensor hole, and Protege's have knock sensors so you will have to figure a new way to mount it.

[justanothermp5]

ah ok, i was tryin to get a jump on putting my forged engine together but i guess not

oh well

[KrayzieFox]

Would someone please sticky this already?!

[Ricktalife]

x2! I never saw this pop up before and was thinking of creating the 1 millionth thread asking if our motors are the same as a normal protege..

[Valk]

the starter on the manual car is a 3 bolt flange design but the starter on a auto is a 2 bolt



uhhhhh when i changed my clutch i only had to take out one bolt to pull the starter... did someone not put some bolts back in?

[yudkib]

this should be stickied. i realize the OP is... well... but still. this has almost every question people ask 10,000x about swapping engines. whats forged, not forged, what needs the cam sensors swapped... etc.

[mildsalsa]

im glad yudkib commented on here or else i would not have located this in time lol... All Useful Info... woot woot

[yudkib]

thank gato. i didnt know this thread existed until he bumped it.

[KrayzieFox]

And it's still not stickied.. instead we have stickies about direct replacement manifolds that don't exist anymore and EMS solutions that no one uses.

[HighSpeed]

LOL^^^^ True

[yudkib]

ive talked with kyle about it, were working on it. expect new stickies in the coming months

[KrayzieFox]

That's good news, but I don't see why it would take months?! You unsticky the old worthless crap that is outdated and no longer relevant, and sticky the new relevant threads. I think we just need a couple mods that actually visit this section of the forum..

Anyway, rant over.. sorry for the off topicness. But this for sure needs to be up there with the daily driven MSP thread. People are popping engines every other week it seems.

[yudkib]

agreed, but said individual is afraid even the dated information is better than none. and he might be right. the fact is, we need NEW stickies, not just moving them around or deleting them.

[gato9lives]

we need a thread on these head units too then ...

[Outlawstar98]

Things can't happen overnight. People have lives. When I get time I'll finish some of the plans I have. There are many I keep pushing back and there are many I'm currently working on.... A stickie must be approved. Just cause it wa requested like yesterday doesn't mean it will happen overnight.

[yudkib]

kyle, this would be a very good thread to mash-up with edwins. add a picture of the vacuum routing for the MSP since thats not an uncommon request.
the more i think about it, the more i think all the OEM stuff should be in one thread... for instance, i have the turbo parts list and the mazdaspeed partial turbo install manual. put those in there too - and maybe roll the reflash in there. yeah its a lot of info for one thread, but its all pertinent, OEM related, and FAQ's.

then do turbo manis, turbos, downpipes, and exhaust in one thread.

have a thread with EMS options, and link to the map libraries and install guide... no need to have three or four stickies on EMS by itself.

thats like 90% of the info at the top of the page in three threads. collapses six stickies into three and adds more, better, and newer information.
for another bonus, put the "mods for a DD" and "winter preparation" into one thread too. four stickies. HUGE improvement.

[haze20]

This thread should actually be erased from the server since Sam can't even use the site anymore.

[yudkib]

that makes no sense. he didnt get banned for being a contributor, he got banned because he broke the rules.

[gato9lives]

im back. Cant believe this never got stickied.
